We don't actually allow any IP specific operations (like match against subnet) through the REST API so not sure the value. The GenericIPAddressField does map to the postgres inet type (I verified that's a true statement on my installs). The netfields lib you shared doesn't seem to like the way django handles certain operations but given the limited way we are using the field not sure the benefit. I think I'd rather take the approach "implement it when you need it" on this one rather than adding another dependency for something we may never use.
